OpenAI Codex vs OpenHands
OpenAI Codex scores 97 to OpenHands's 95 on public evidence for autonomous coding agent, and they rank #1 and #3 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
OpenAI Codex
OpenAI's coding agent, available as an open-source CLI, an IDE extension, and a cloud sandbox in ChatGPT.
+ Cloud mode runs many tasks in parallel sandboxes and opens PRs for each.
− Native Windows support in the CLI arrived late and sandboxing can block legitimate commands.
OpenHands
Open-source platform for autonomous coding agents, formerly OpenDevin, with a hosted cloud option.
+ Top-ranked open agent on SWE-bench that you can run on your own infrastructure.
− Docker-based local setup is heavy and the UI is rougher than commercial agents.
